Hope I get this right, I’m no german but I understand it mostly:
Video 1:
T: “I, I’m Thomas D, and I’m a warrior”
T; “An all-destroying war machine”
T: “Nothing, and no one can stop me!”
S: nagging voice: “Nothing and no one can stop me…”
T: “And what can you do then?” (bit loose translation, it’s more like and what can you do for something special)
S: ninja noises
S: “(can’t hear m while whispering… and I’m invisible”
T: stunned “I… am… a .... warrior….”
S: chuckles “what do you play?”

video 2:
S: “hi, I’m Smudo. I’m a rogue”
S: “A master of <something :S>, hits fast, merciless, icecold!”
T: “Your forgetting something”
S: “huh?”
T: “That your damm good at running”
S: “Thank you, you warrior <something>!”
S: “I’m smudo, and I’m a rogueeeee”
T: “What do you play?”

Sorry for the missing words :S

Confirm accurate on both translations, I think the bit on the second you couldnt make out is “thank you you war cadet” but that last words really hard to make out.

Excellent, thanks guys :D

That other missing word might be “tau” which in German is tying something up with a rope (he says it while stunlocking someone)
